Piezas Faltantes connects a disregarded population in Colombia — family members of people who went missing due to the political armed conflict — with audiences in big cities, preserving the memory and dignity of their loved ones by shining a light on their stories. The intervention is intended to defeat a big hurdle between those who had suffered the scourge of the conflict and those who had not: indifference. Through a lens of empathy, big audiences in Colombian cities connect with the stories of those who disappeared and never came back, by involving a storytelling strategy that includes the active participation of the families, artists, social organizations and the public itself in a collaborative art experience that addresses a common goal: no more victims.
